Universal Gcode Sender

A full featured gcode platform used for interfacing with advanced CNC controllers like GRBL
and TinyG.
Universal Gcode Sender is a self-contained Java application which includes all external dependencies,
that means if you have the Java Runtime Environment setup UGS provides the rest.

GRBL 1.1 Features

Overrides and Toggles

Platform version only. Easily control the real time feed and speed overrides by
enabling the Overrides widget in the Window menu.

Jog Mode

With older versions of GRBL UGS is pretty reliable when it comes to jogging, but
there are limitations. With GRBL 1.1 this is no longer the case when using the
new JOG MODE syntax. This first-class jog mode guarantees the GCODE state will
be unaltered, and also allows you to stop a jog while it is in progress. UGS
uses this new syntax automatically when it detects a version of GRBL which
supports it. During a jog use the STOP action to stop an in-progress jog:

>> $J=G21G91X0.7F11
ok
>> $J=G21G91Y0.7F11
ok
>> $J=G21G91Z-0.7F11
ok

Pin State Reporting

Platform version only. New flags have been added to the controller state window
to indicate when various external switches are enabled.

Message resolution
GRBL removed most help and error messages to make room for new features on the
micro controller, they are now provided as data files in the grbl source code.
UGS uses these data files to resolve all error codes and setting strings.
